Description

Double Bearing Fishing Reel

technical field

The present invention relates to a dual-bearing fishing reel, and more particularly to a dual-bearing fishing reel having a clutch mechanism for connecting a handle and a reel and releasing the connection between the handle and the reel.

Background technique

In the double-bearing fishing reel, a clutch mechanism is provided between the handle and the spool (for example, refer to Patent Document 1). The clutch mechanism connects and uncouples the handle and the spool. The clutch mechanism has a clutch yoke and a strut member supporting the clutch yoke.

For example, in the support member of patent document 1, two support parts and the main-body part for attaching to a frame are integrally formed. In Patent Document 2, two support members are directly attached to the frame. These strut members are generally made of metal because they need to support a clutch fork that moves a load-bearing pinion gear in the axial direction of the spool.

【Technical problem to be solved by the invention】

In the conventional dual-bearing fishing reel, when water, salt water, or the like adheres to the metal support member, there is a possibility that the support member may be corroded. Here, when the metal pillar member is corroded, the strength and shape of the pillar member are impaired. In addition, the strut member and the clutch fork are stuck together by the precipitated salt, or the roughness of the strut member surface becomes large. That is, in the conventional strut member, there is a concern that the clutch fork cannot be properly guided in the axial direction.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a dual-bearing fishing reel capable of appropriately guiding a clutch fork.

【Technical solutions for solving technical problems】

A dual-bearing fishing reel according to an aspect of the present invention has a clutch mechanism that connects the handle and the spool and releases the connection between the handle and the spool. This dual-bearing fishing reel has a metal frame, clutch fork, and resin guide member.

A metal frame supports the handle shaft of the handle. The clutch fork is used to switch the clutch mechanism between the connected state and the disconnected state. The guide member made of resin includes: a main body attached to the frame; and a support part integrally formed with the main body and guiding the clutch fork in the axial direction.

In this dual bearing reel, since the support part is made of resin, corrosion of the support part can be prevented. That is, in the present dual-bearing fishing reel, deformation of the support portion and reduction in strength of the support portion due to corrosion do not occur, and therefore, the clutch fork can be appropriately guided by the support portion. In addition, it is possible to prevent the sticking of the support portion and the clutch fork due to precipitates and prevent an increase in the surface roughness of the support portion, so that the clutch fork can be appropriately guided by the support portion.

In addition, in the present double bearing reel, the main body is made of resin, so the main body can be prevented from being corroded. According to this, the attitude change of the support part due to the corrosion of the main body part does not occur, and therefore, the clutch fork can be more appropriately guided by the support part.

In the twin-bearing fishing reel according to another aspect of the present invention, the support portion has a guide shaft. The guide shaft protrudes from the main body. At least a part of the guide shaft is formed in a substantially cylindrical shape. In this case, a reinforcement member is disposed on the inner peripheral portion of the guide shaft.

In this configuration, since the reinforcing member is disposed on the inner peripheral portion of the guide shaft, the strength of the guide shaft can be increased. Accordingly, the clutch fork can be appropriately guided by the support portion (guide shaft).

In the dual-bearing fishing reel according to another aspect of the present invention, it is preferable that the reinforcing member is made of metal. According to this configuration, the strength of the protruding portion can be further increased, and the clutch fork can be appropriately guided by the support portion (protruding portion).

The double-bearing fishing reel according to another aspect of the present invention further includes a clutch cam that moves a clutch fork in the axial direction. The main body is disposed between the frame and the clutch cam.

With such a configuration, the clutch fork can also be appropriately guided by the support portion (protrusion portion).

【Invention effect】

In the dual bearing fishing reel of the present invention, the clutch fork can be properly guided.

The spool shaft 15 is configured to be rotatable relative to the reel body 3 . For example, as shown in FIG. 2 , one end portion of the spool shaft 15 is rotatably supported by the first side plate 9 a via a bearing 16 a arranged in the bearing housing portion 16 . The other end of the spool shaft 15 is rotatably supported by the second side plate 9b via a bearing 16b. An engagement pin 15 a constituting a clutch mechanism 25 is attached to the spool shaft 15 .

<Clutch operating part>

As shown in FIGS. 1 and 3 , the clutch operating member 11 is disposed at the rear of the reel main body 3 . The clutch operating member 11 is connected to a clutch control device 30 . The clutch operating member 11 is configured to be movable between a clutch engaging position (see the solid line in FIG. 1 ) and a clutch disengaging position (see the broken line in FIG. 1 ). The clutch operating member 11 is also used as a thumb rest for thumb-controlled spool thumbing operations.

<rotation transmission mechanism>

The rotation transmission mechanism 13 is used to transmit the rotation force from the handle 4 to the spool 7 . As shown in FIG. 3 , for example, the rotation transmission mechanism 13 has a handle shaft 17 , a drag mechanism 19 , a drive gear 21 , and a pinion 23 (see FIG. 2 ).

The handle 4 is installed on the handle shaft 17 . The handle shaft 17 is rotatably supported by the metal frame 5 . Specifically, the handle shaft 17 is rotatably supported by the second side cover 6 b and the frame 5 . For example, the handle shaft 17 is rotatably supported by the second side cover 6b via a one-way clutch (not shown) that prohibits rotation in the wire releasing direction. Moreover, the handle shaft 17 is rotatably supported by the 2nd side plate 9b via the bearing (not shown).

The drag mechanism 19 transmits the rotation of the handle shaft 17 to the drive gear 21, and brakes the rotation of the spool 7 at the time of unwinding. As shown in FIG. 3 , the drag mechanism 19 is arranged between the handle shaft 17 and the driving gear 21 .

The drive gear 21 is rotatably attached to the handle shaft 17 . As shown in FIG. 3 , the rotation of the handle shaft 17 is transmitted to the drive gear 21 via the drag mechanism 19 . Here, a helical gear is used as the driving gear 21 . In addition, when a predetermined torque or more acts on the spool 7 at the time of unwinding, the drag mechanism 19 operates to rotate the drive gear 21 with respect to the handle shaft 17 .

The pinion 23 transmits the rotation of the drive gear 21 to the spool shaft 15 . As shown in FIGS. 2 and 3 , the pinion gear 23 is formed in a substantially cylindrical shape, and is disposed on the outer peripheral side of the spool shaft 15 .

As shown in FIG. 2 , the pinion gear 23 has a helical tooth portion 23a, an engaging groove 23b, and a small diameter portion 23c. The tooth portion 23 a meshes with the drive gear 21 .

The engagement groove 23b is formed at the end of the pinion 23 and extends in the radial direction. The outer peripheral surface of the cylindrical portion in which the engaging groove 23b is formed is rotatably supported by a guide member 45 (described later) via a bearing 24 (see FIG. 2 ). The small-diameter portion 23c is formed between the tooth portion 23a and the engaging groove 23b. A clutch fork 41 (described later) is engaged with the small-diameter portion 23c.

<clutch mechanism>

The clutch mechanism 25 is configured to be able to connect the handle 4 and the spool 7 and to be able to release the connection between the handle 4 and the spool 7 . As shown in FIG. 2 , the clutch mechanism 25 is composed of the engagement groove 23 b of the pinion gear 23 and the engagement pin 15 a of the spool shaft 15 .

For example, when the pinion 23 moves away from the spool 7 along the spool shaft 15 to release the engagement between the engagement groove 23b and the engagement pin 15a of the spool shaft 15, the clutch is disengaged (connected). off state). In this case, the spool 7 can freely rotate.

On the other hand, when the pinion gear 23 moves toward the spool 7 along the spool shaft 15 and engages the engaging groove 23b with the engaging pin 15a, the clutch is engaged (connected state). In this case, the spool 7 rotates in conjunction with the rotation of the handle shaft 17 .

<clutch control device>

The clutch control device 30 is configured to be able to control the clutch mechanism 25 in accordance with the operation of the clutch operating member 11 . As shown in FIG. 3 , the clutch control device 30 has a clutch fork 41 , a clutch cam 43 , and a guide member 45 made of resin.

(clutch fork)

The clutch fork 41 is a member for switching the clutch mechanism 25 between the clutch engaged state and the clutch disengaged state. As shown in FIG. 3 , the clutch fork 41 is guided in the spool axial direction by the clutch cam 43 and the guide member 45 .

As shown in FIG. 2 , the clutch fork 41 has an engaging recessed portion 41 a capable of engaging with the pinion gear 23 and a pair of guide holes 41 b. The engaging recessed portion 41 a engages with the small-diameter portion 23 c of the pinion 23 .

The pair of guide holes 41b penetrate the clutch fork 41 in the spool axial direction. A guide shaft 48 (described later) is inserted through each guide hole 41b. Both ends of the clutch fork 41 are engaged with the clutch cam 43 .

(clutch cam)

The clutch cam 43 is a member for moving the clutch fork 41 in the axial direction of the spool. The clutch cam 43 is arranged on the guide member 45 so as to be rotatable about the spool axis X. As shown in FIG.

The coupling member 42 is attached to the clutch cam 43 . The connecting member 42 connects the clutch operating member 11 and the clutch cam 43 . When the clutch operating member 11 is operated, the clutch cam 43 rotates via the connecting member 42 .

The clutch cam 43 is arranged on the outer peripheral side of a second cylindrical portion 46c (described later) of the guide member 45, and is rotatable around the second cylindrical portion 46c. The clutch cam 43 is axially positioned by the positioning member 50 . The positioning member 50 is fixed to the second side plate 9b by a fixing member such as a screw member 50a.

The clutch cam 43 has a cam portion 43 a for guiding the clutch fork 41 in the axial direction. When the clutch cam 43 is rotated by the operation of the clutch operating member 11 , the cam portion 43 a presses both end portions of the clutch fork 41 . Then, both end portions of the clutch fork 41 move in a direction away from the spool 7 in the spool axial direction. Accordingly, the clutch mechanism 25 can be switched from the clutch engaged state to the clutch disengaged state.

On the other hand, when the clutch return mechanism (not shown) is activated by the operation of the handle 4, the clutch cam 43 rotates in the direction opposite to the rotation direction described above. Then, both ends of the clutch fork 41 move toward the spool 7 in the spool axial direction. Accordingly, the clutch mechanism 25 can be switched from the clutch disengagement state to the clutch engagement state.

(guide parts)

The guide member 45 guides the clutch fork 41 in the spool axial direction. As shown in FIG. 3 , the guide member 45 is attached to the frame 5 . As shown in FIGS. 4 and 5 , the guide member 45 has a main body portion 46 and a guide portion 47 (an example of a support portion). The guide member 45 also has a reinforcing member 49 (see FIG. 5 ).

As shown in FIG. 3 , the main body portion 46 is attached to the frame 5 . As shown in FIGS. 4 and 5 , the main body portion 46 has a fixing portion 46 a, a first cylindrical portion 46 b, and a second cylindrical portion 46 c.

The fixing portion 46a is formed in a substantially plate shape. The fixing portion 46 a is disposed between the frame 5 and the clutch cam 43 . The fixed part 46a is fixed to the frame 5, for example, the 2nd side plate 9b by a fixing mechanism, for example, the screw member 51 (refer FIG. 3).

The first cylindrical portion 46b is integrally formed with the fixing portion 46a. The first cylindrical portion 46b penetrates through the fixing portion 46a in the spool axial direction, and protrudes from the fixing portion 46a. The 1st cylindrical part 46b is arrange|positioned in the 2nd opening 9e provided in the 2nd side plate 9b (refer FIG. 2). The spool shaft 15 is disposed on the inner peripheral side of the first cylindrical portion 46b.

The second cylindrical portion 46c is integrally formed with the fixing portion 46a. The second cylindrical portion 46c connects a pair of guide shafts 48 (described later) in the circumferential direction. The clutch cam 43 (see FIG. 3 ) is arranged on the outer peripheral portion of the second cylindrical portion 46c.

As shown in FIG. 5 , the inner diameter of the second cylindrical portion 46c is larger than the inner diameter of the first cylindrical portion 46b. The bearing 24 (refer FIG. 2) which supports the pinion gear 23 is arrange|positioned at the annular step part 46d formed by the 1st cylindrical part 46b and the 2nd cylindrical part 46c.

As shown in FIGS. 4 and 5 , the guide portion 47 is integrally formed with the main body portion 46 . The guide portion 47 guides the clutch fork 41 in the spool axial direction. The guide portion 47 has a pair of guide shafts 48 (an example of at least two protrusions) protruding from the main body portion 46 .

A pair of guide shafts 48 are integrally formed with the main body portion 46, for example, the fixing portion 46a. A pair of guide shafts 48 protrude axially toward the spool from the fixing portion 46a, respectively. The pair of guide shafts 48 are arranged at intervals from each other in the circumferential direction.

The pair of guide shafts 48 are inserted through the pair of guide holes 41 b of the clutch fork 41 . In this state, coil springs 44 are disposed on the outer circumference of each guide shaft 48 (see FIG. 2 ). For example, the coil spring 44 is arranged on the outer periphery of each guide shaft 48 in a state of being compressed between the clutch fork 41 and the second side cover 6b.

For example, when the clutch mechanism 25 is in the clutch-engaged state, when the clutch cam 43 is rotated by the operation of the clutch operating member 11, the clutch fork 41 is guided by the pair of guide shafts 48 to move away in the spool axial direction. The direction of the spool 7 moves. Accordingly, the clutch mechanism 25 can be switched from the clutch engaged state to the clutch disengaged state.

On the other hand, when the clutch return mechanism (not shown) is actuated by the operation of the handle 4, the clutch fork 41 is biased by the coil spring 44, and moves closer in the axial direction of the spool along a pair of guide shafts 48. The direction of the spool 7 moves. Accordingly, the clutch mechanism 25 can return from the clutch disengagement state to the clutch engagement state.

Next, the structure of the guide shaft 48 will be described in detail. As shown in FIG. 5 , at least a part of the guide shaft 48 is formed in a substantially cylindrical shape. A reinforcing member 49 is disposed on the inner peripheral portion of the guide shaft 48 .

Here, a part of the guide shaft 48 is formed in a substantially cylindrical shape. The guide shaft 48 has a hollow first shaft portion 48a and a solid second shaft portion 48b. The first shaft portion 48a is formed integrally with the fixing portion 46a, and protrudes from the fixing portion 46a toward the spool axial direction. The base end portion of the first shaft portion 48 a corresponds to the base end portion of the guide shaft 48 .

The first shaft portion 48a is formed in a substantially cylindrical shape. A reinforcing member 49 is disposed on the inner peripheral portion of the first shaft portion 48a, that is, the hole portion 48c. The hole portion 48c of the first shaft portion 48a opens on the second side plate 9b side of the frame 5 .

The second shaft portion 48b is integrally formed with the first shaft portion 48a. The second shaft portion 48b extends in the spool axial direction from the tip end portion of the first shaft portion 48a. The tip end of the second shaft portion 48 b corresponds to the tip end of the guide shaft 48 . The second shaft portion 48b is formed in a solid rod shape.

The reinforcing member 49 is a member for reinforcing the strength and rigidity of the guide shaft 48 . The reinforcing member 49 is made of metal. For example, the reinforcing member 49 is a metal pin member.

The reinforcement member 49 is disposed on the inner peripheral portion of the guide shaft 48 on the base end side of the guide shaft 48 . The reinforcing member 49 is fitted into the hole portion 48c of the first shaft portion 48a. Specifically, the reinforcing member 49 is fitted from the second side plate 9 b side of the frame 5 toward the hole 48 c of the first shaft portion 48 a. Accordingly, with the guide member 45 attached to the second side plate 9b of the frame 5, the hole portion 48c of the first shaft portion 48a and the reinforcing member 49 are covered by the second side plate 9b. Therefore, even if the reinforcing member 49 is made of metal, adhesion of water, salt water, and the like can be prevented.

Here, the length L1 of the reinforcing member 49 in the axial direction is longer than the axial distance L2 between the facing surface S1 of the fixing portion 46a facing the second side plate 9b and the clutch cam in the clutch-engaged state. 43 is the distance between the abutting surfaces S2 of the clutch fork 41 . Accordingly, the fixed end side of the guide shaft 48 can be reliably reinforced by the reinforcing member 49 .

In the present dual bearing reel 1 described above, since the guide member 45 (the main body portion 46 and the guide portion 47 ) is made of resin, the guide portion 47 can be prevented from being corroded. That is, in this double-bearing fishing reel 1, deformation of the guide portion 47 due to corrosion and reduction in the strength of the guide portion 47 due to corrosion do not occur, so the clutch fork can be well guided by the guide portion 47. 41. In addition, adhesion between the guide portion 47 and the clutch fork 41 and an increase in surface roughness of the guide portion 47 can be prevented, so that the clutch fork 41 can be appropriately guided by the guide portion 47 .

In addition, in the dual-bearing fishing reel 1, the guide part 47 is formed integrally with the main body part 46, so that there is no need to use a metal fixing member for fixing the guide part 47 to the main body part 46 as in the prior art. That is, in the dual-bearing reel 1 , since the attitude change of the guide portion 47 does not occur due to corrosion of the metal fixing member, the clutch fork 41 can be more appropriately guided by the guide portion 47 .

Furthermore, in the present dual-bearing fishing reel 1, the reinforcing member 49 is arranged on the inner peripheral portion of the guide shaft 48, so the strength of the guide shaft 48 can be increased. Accordingly, the clutch fork 41 can be appropriately guided by the guide shaft 48 .
